[PATCH v3 07/11] powerpc: Add support to take additional parameter in MASKABLE_* macro

Madhavan Srinivasan maddy at linux.vnet.ibm.com
Tue Nov 15 05:04:48 AEDT 2016


To support addition of "bitmask" to MASKABLE_* macros,
factor out the EXCPETION_PROLOG_1 macro.

Currently soft_enabled is used as the flag to determine
the interrupt state. Patch extends the soft_enabled
to be used as a mask instead of a flag.

Make it explicit the interrupt masking supported
by a gievn interrupt handler. Patch correspondingly
extends the MASKABLE_* macros with an addition's parameter.
"bitmask" parameter is passed to SOFTEN_TEST macro to decide
on masking the interrupt.
